Samsung's new Galaxy S 4 is also packing another feature, for your health. It has a built in pedometer and an app called S Health. The phone has built in sensors to measure the temperature and humidity of your location, a body scale and heart rate monitor.

"The combination of sensors built within the device systematically and automatically monitors your health, surroundings and so much more to help improve your quality of life," says Samsung.

The S Health app will also work with third party devices such as glucose meters and blood pressure monitors.

Going head on to Nike's market, Samsung also mentioned the S Band Bracelet, which works similar to Nike Fuelband or Jawbone Up.
